Polishing pastes containing particles are used in the dental laboratory to polish ground abutments. The polishing agents must be removed without residue after the polishing work is completed. Especially in plastic abutments, e.g. made of PEEK, this is not possible without ultrasound. The threads of the screws must not be contaminated with polishing particles under any circumstances, as jamming the screw can damage the implant.
With ultrasonic cleaning, even the finest gaps can be thoroughly cleaned and the polishing agents completely removed.
